Mass Rebuild - SOP


Periodically we do mass rebuilds of rawhide during the development cycle. This SOP will outline the steps necessary to do this.


This assumes that the mass rebuild has already been approved and scheduled via release engineering and FESCo. Coordinate with infrastructure as well for any needed koji updates.

This also assumes that the mass rebuild does not need to be done in dependency order, and that the mass rebuild does not involve a ABI change.

Set up a web page for maintainers

First, describe the mass rebuild for maintainers; why it's being done, and how they can opt out. See the Fedora 12 example.

Update releng scripts

Release engineering scripts for mass rebuilds live in the releng git repository. You need to edit the following scripts:


Change the following items:

  • the build tag, holding tag, and target tag should be updated to reflect the Fedora release you're building for
  • the 'epoch' tag should be updated to the point at which all features that the mass rebuild is for have landed in the build system (and a newRepo task completed with those features)

Create the rebuild tag

The clone-tag command is a convenient command to use for creating the rebuild tag.

$ koji clone-tag --help
Usage: koji clone-tag [options]  <src-tag> <dst-tag>
(Specify the --help global option for a list of other help options)

-h, --help     show this help message and exit
-v, --verbose  show changes
-n, --test     test mode

It not only creates the tag, but it will also copy over all package ownership info, package configs, and tag all the latest packages from the source. The end result of running this command is a functional up to date new tag that is a snapshot of the source tag in question. Running this command later will update the rebuild tag with any changes from the source tag.

For example, if we wanted to create a rebuild tag for Fedora 12 development we would issue:

koji clone-tag dist-f12 dist-f12-rebuild

We also want to prevent people from manually tagging packages. To accomplish this we lock the tag with edit-tag:

koji edit-tag --lock dist-f12-rebuild

Mass bump the release of the packages in CVS

Tag the packages in CVS

Submit the builds

Track the failures
